Ok so I'm building my first rig which happens to use sli. My question is wether I install 1 card first and get it running with new drivers then add the other, or can I put them both in off the bat. My guess is option 1, but I want some clarification before I screw up. and yes the mobo psu and cards are sli compatible, 2x16, so at least I didn't screw that up yet. Any help would be greatly appreciated and I apologize if this has been discussed to death. I tried to search. also I am hoping to be able to refer back here if I have any issues as I understand this is the best community resource on this topic.
